Ageing breakthrough: Scientists create “hyper-long” telomeres without gene editing

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

Scientists have successfully created mice with significantly longer telomeres than normal, resulting in a drop in molecular ageing, without using genetic manipulation.

Telomeres, which are found at the end of all animals’ chromosomes, are thought to be vital to ending ageing, as their shortening as we age is a key factor in cellular ageing and the onset of age-related disease. However, when they are lengthened beyond normal levels in mice, they have the precise opposite effect, protecting against ageing and related diseases, and increasing lifespan.

The mice, which are chimeras carrying both regular and “hyper-long” telomeres, were created using a technique based on epigenic changes, where embryonic stem cells are expanded in vitro, prompting changes to telomeres.

Genetically modified bacteria converts CO2 into liquid fuels

Posted by in categories: bioengineering, energy, genetics, transportation

Daniel G. Nocera, the Harvard professor who made headlines five years ago when he unveiled an artificial leaf, recently unveiled his latest work: an engineered bacteria that converts hydrogen and carbon dioxide into alcohols and biomass. One can be used directly as fuel to power vehicles that run on conventional fuels, while the other can be burned for energy.

The Coming Genetic Editing Age of Humans Won’t Be Easy to Stomach

Posted by in categories: 3D printing, bioengineering, biotech/medical, genetics, government, health, transhumanism, transportation

My new article for Vice Motherboard on extreme biohacking that compares the Uncanny Valley to Speciation Syndrome:


Transhumanism tech like CRISPR, 3D printing, and coming biological regeneration of limbs will not only change lives for those that have deformities, but it will change how we look at things like a person with a three-foot tail and maybe even a second head.

At the core of all this is the ingrained belief that the human being is pre-formed organism, complete with one head, four limbs, and other standard anatomical parts. But in the transhumanist age, the human being should be looked at more like a machine—like a car, if you will: something that comes out a particular way with certain attributes, but then can be heavily modified. In fact, it can be rebuilt from scratch.

More Efficient CRISPR Gene Editing May Potentially Help Cure Diseases

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

Awesome.


Researchers have developed a new gene editing tool that is more efficient and easier to use. CRISPR-EZ addresses the issue of target RNA accuracy and embryo viability in IVF transgenic mice.

A Guide to CRISPR Gene Activation

Posted by in categories: bioengineering, biotech/medical, genetics

“The possibility to selectively activate genes using various engineered variants of the CRISPR-Cas9 system left many researchers questioning which of the available synthetic activating Cas9 proteins to use for their purposes. The main challenge was that all had been uniquely designed and tested in different settings; there was no side-by-side comparison of their relative potentials,” said George Church, Ph.D., who is Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard University, leader of its Synthetic Biology Platform, and Professor of Genetics at Harvard Medical School. “We wanted to provide that side-by-side comparison to the biomedical research community.”

In a study published on 23 May in Nature Methods, the Wyss Institute team reports how it rigorously compared and ranked the most commonly used artificial Cas9 activators in different cell types from organisms including humans, mice and flies. The findings provide a valuable guide to researchers, allowing them to streamline their endeavors.

The team also included Wyss Core Faculty Member James Collins, Ph.D., who also is the Termeer Professor of Medical Engineering & Science and Professor of Biological Engineering at the Massachusetts Institute of Technology (MIT)’s Department of Biological Engineering and Norbert Perrimon, Ph.D., a Professor of Genetics at Harvard Medical School.

HIV Genes Have Been Cut Out of Live Animals Using CRISPR

Posted by in categories: bioengineering, biotech/medical

For the first time ever, scientists were able to successfully cut out the HIV genes from live animals, and they had over a 50% success rate.

A significant milestone was achieved today in the fight against HIV—scientists led by Kamel Khalili of the Comprehensive NeuroAIDS Center at Temple University just reported that, for the first time, HIV genes have been successfully eliminated from the genomes of animals infected with the virus.

‘Radical life extension’ coming, futurist says

Posted by in categories: 3D printing, bioengineering, computing, life extension, nanotechnology, neuroscience, Ray Kurzweil

KITCHENER — Big jumps in life expectancy will begin in as little as 10 years thanks to advances in nanotechnology and 3D printing that will also enable wireless connections among human brains and cloud computers, a leading futurist said Thursday.

“In 10 or 15 years from now we will be adding more than a year, every year, to your life expectancy,” Ray Kurzweil told an audience of 800 people at Communtech’s annual Tech Leadership conference.

Kurzweil, a futurist, inventor and author, as well as a director of engineering at Google, calls this “radical life extension.”

Scientists prove effectiveness of gene editing system in eliminating HIV from DNA of CD4+ T-cells

Posted by in categories: bioengineering, biotech/medical

Hope for HIV patients.


In 2014, a team of researchers in the Lewis Katz School of Medicine at Temple University became the first to successfully eliminate the HIV-1 virus from cultured human cells. Fewer than two years later, the team has made further strides in its research by eliminating the virus from the genome of human T-cells using the specialized gene editing system they designed.

In a new study published in Scientific Reports, the researchers show that the method can both effectively and safely eliminate the virus from the DNA of human cells grown in culture.
